摘要：
The utility model relates to agricultural machinery, in particular to tillage units for surface tillage. The combined soil cultivating unit includes a frame on which vertical columns with axles are mounted and spherical discs having an adjustable angle of attack and deep rippers mounted on the axles are rotatably mounted. At the rear of the unit are transport and technological wheels. On the periphery of each spherical disk, recesses are made in the form of a semicircle, and the cutting edge of the spherical disks is sharpened. A roller attachment is attached to the back of the unit frame, containing sequentially mounted rollers, an H-shaped frame, brackets and rods. A nut and a spring are installed on each rod. Each roller contains an axis, side and intermediate disks mounted on the axis at equal intervals in the horizontal plane, rippers. On the periphery of the side and intermediate discs, triangular recesses are made. The rippers are mounted in triangular recesses of the side and intermediate discs so that they form a helical line. The direction of the helical line of the front roller starts from its longitudinal axis of symmetry and is directed towards the side discs. The direction of the helical line of the rear roller starts from the side discs and is directed to the longitudinal axis of symmetry of the roller. The rippers in the cross section are square and twisted along the entire length by an angle α relative to their longitudinal axis of symmetry so that the sharp edges of each ripper form helical lines, and the sharp edges of the rippers are directed in different directions from the geometric axes of rotation of the rollers installed in series. Provides improved soil cultivation. 3 ill.Полезная модель относится к сельскохозяйственному машиностроению, в частности к почвообрабатывающим агрегатам для поверхностной обработки почвы.
